PRINTING-MACHINE.

SEECIFIGATION forming part of Letters Patent No. 735,646, dated August4, 1903. Application iled May 14, 1894. Renewed January 12, 1903. SerialNo. 138,662. (No model.)

To @ZZ whom it may concern:

Be it known that I, HENRY A. WISE WOOD, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Improvement in Printing-Machines, ofwhich the following is a specification.

This invention relates to that class of printing-presses which are knownas travelingcylinder web-printing presses; and the objects of myinvention are to provide a compact, durable, 'and convenientconstruction Which will occupy very little floor-space and a press whichmay be operated at a high speed which will require comparatively littlepower.

To these ends my inventionconssts of the parts and combinations of partsas hereinafter described,and more particularly pointed out in the claimsat the end of this specification.

In the accompanying two sheets of dra-wings, Figure 1 is a sideelevation of a printingpress constructed according to my invention, andFig. 2 is a diagrammatic sectional View of the same.

Referring to the drawings and in detail,-A represents a locomotive ortraveling impression-cylinder which is journaled in a suitable carriageor carriages E, fitted on Ways on the main frame, which impression-cylinder is adapted to cooperate with a stationary formbed C. Journaledor mounted in the carriage E inany approved manner, at each side of theimpression-cylinder A, I provide formrollers F, which cooperateWithink-tables T and with distributing-rollers'J, which latter may besupplied with ink from ink-fountains K of any of the usual or preferredconstructions by any suitable means,` as ductor-rolls, as shown. Ifdesired, springs may be used to keep the form-rollers in place'in thecarriage.

B designates the second rimpression-cylinder, which is journaled in asuitable carriage E', mounted on guides on the frame,as shown, and whichimpression cylinder cooperates with a' stationary form-bed D. Journaledor mounted in the carriage F. are form-inking Yrollers FQ whichcooperate with ink-table T',

and distributing-rollers J', to which in'k is supplied from thefountains K', as described in connection with the firstimpression-cylinder.

The stationary form-beds C and D face outwardly and are secured to sideframes 10 on the press. rThe essential feature of this arrangement isthat the beds should be arranged substantially back to back and faceoutwardly, no matter whether they are relatively inclined or not.

My invention consists, in the first place, in the new manner in whichthe web is led through a press of this general description. The web w isunwound from the Web-roll W and is then led up, over, and around theconstantly-running feeding-in roll 11, with which cooperate the endlesstapes 12, which pass over the tape-pulleys 13, 14., and 15, whichtape-pulleys maybe driven by suitable gearing. From the feeding-in roll11 the web passes down under the looping-in roller 16, up around theguide-roller 17,0ver and around the guide-roller 18, carried by thecylindercarriage E, down, under, and around the rst impression-cylinderA, over the roller 19, also carried by the cylinder-carriage E, over andaround guide-rollers 20 and 21, down between 'the two stationaryform-beds C and D, un-

der and around the guide-roller 22, under and around the roller 23,which may be made adjustable in any of the approved ways, up around theguide-roller '24, over and around the guide-roller 25, carried by thecylindercarriage E', down, under, and around the sec- -ondimpression-cylinder B, over the guide 26,

also carried by the carriage E', around the guide-roller 27, up, over,and around the looping-out roller 28, down, over, and around theconstantly-running feeding-out roller 29, with which cooperate thefeeding-Out tapes 30, which pass over tape-pulleys 30, 32, and 33, whichmay be driven by any suitable gearing, (not necessary here to show.)From the constantly-running feeding-out roller 29 the web may be led toany preferred form of cutting and folding or delivery mechanism. By thispassage of the web through the press it will be seen that a very directand short path for the web is provided and one that contains very fewcorners and also one through which the web can be quickly threaded;also, it

will be seen that the web passes from the first IOO looper to the firstpress over a very slight corner and from the second press to thelooping-out roller over a very slight corner. This enables the loopersto put almost a direct pull upon the web; also, as hereinafterdescribed, it will be seen that as the im pression-cylinders preferablyare reciprocated in opposite direction that the strain or trend of theweb from each impression-cylinder will counterbalance each other,whereby the press can be run at a very high rate of speed. Of course thesame ad vantages would be obtained and it would be within the scope ofmy invention to run the web through the press in the oppositedirection-that is, to lead the web in over the looping-roller 28 and outover the looping-roller 16.

The gearing for driving the press which I may employ is substantiallyinclosed by the stationary form-beds C and D and the side frames l0 andmay be arranged as follows: 320 designates the powershaft, to whichpower may be applied in any of the ordinary or preferred manners.Fastened to the powershaft 320 is a pinion 330, which meshes with anintermediate 33, which intermediate 33 drives a gear 34, fastened on thedriving-shaft 35. Secured on the inner end of the drivingshaft 35 is acrank-disk 36, which carries a crank-pin 37, which connects by pitman 38to a sector 39, pivoted on a transverse stud or shaft 40. Meshing withand engaging the sector 39 is a gear 4l, mounted on ashaft 42, journaledin the side frames, and this shaft 42 carries gears 43, preferably onthe outside of each frame, as shown. The gears 43 mesh with and drivegears 44 and'45, which in turn mesh with and engage racks 46 and 47,carried by the cylinder-carriages E and E, and I preferably use gears 44and 45 on each side of the press, so that the mechanism will square. Bythis means it will be seen that I have provided a strong and efficientdriving mechanism which is adapted to move the impression-cylinderspreferably in opposite directions and one which has its vibrating partshoused within the framing. By this means the impression-cylinders willcounterbalance each other and can be run at a high rate of speed.

In some instances I contemplate arranging the gears 43, 44, and and therack-bars just inside of the frames, the gears 44 and 45 being set upthrough stationary beds, so that the entire gearing will be out of theway.

The gearing for driving the web-feeding devices may be arranged in anyconvenient manner, and, as shown in the drawings, 50 designates a gearwhich meshes with and engages the intermediate 33. Secured to the gear50 I provide a suitable heart-shaped cam 52, which engages and actuatesa roller mounted on a bell-crank lever 53. The shaft on which thebell-crank lever 53 is mounted is preferably carried across the press,and a similar' lever 53 is arranged on the other side of the press.Springs 530 are arranged, as shown, in connection with these bell-cranklevers, so as to keep the roller against the cam. The bell-crank leversat one end are connected with and actuate the looping-in roller by meansof pitmen 54, as shown. The opposite arms of the bellcrank levers 53 areconnected by pitmen 55 with bell-crank levers 56, which are connected bypitmen 57 with the pivoted levers 58, which are connected to and actuatethe looping-out roller by means of pitmen 59, as shown.

The cam, gearing, and connections before described are so proportionedthat the cam will make two turns for each forward and backward movementor complete cycle of the impression-cylinders, so that the web will befed while the impression-cylinders are off impression in eitherdirection, whereby two perfected sheets will be printed at each cycle.

The gearing for driving the feeding-in and feeding-out rollers may bearranged as follows: As shown, 60 designates a change-gear, which isjournaled on a stud in the sweep 6I and which change-gear 60 meshes withthe gear 34. The gear 60 has on the other side of the sweep agear 600,which by setting the sweep may be made to mesh with a gear 62, securedto or upon the same shaft with a bevel-gear 63, the bevel-gear 63driving the horizontal shaft 65 by means of the bevelpinion 64, asshown. The horizontal shaft 65 is geared at one end by the bevel-gears66 and 67 to actuate and drive the feeding-in roll Il. At its other endthe shaft 65 is geared to a vertical shaft by means of the bevel-gears68 and 69, and the shaft 70 is geared with and drives the feeding-outroller 29 by means of the bevel-gears 7l and 72.

By changing the gear 60 and the cam 52 various lengths of sheets withinthe limits of the press may be printed and delivered.

It will thus be seen that I have provided a strong, simple, and compactprinting machine with a very simple and direct-driving mechanism, whichmay be actuated with comparatively little power, as the parts arearranged to substantially counterbalance eachother, and one in which thetrends on the web from the two impression-cylinders will offset eachother. Also it will be seen that I have provided a very direct path oftravel for the web, which is fed into the machine at one side and fedout of the machine at the opposite side in such a position that it canbe readily carried to any folding or delivering mechanism.

I am aware that many changes in the design of the gearing andarrangement of the various operating parts can be made by those who areskilled in the art, and I do not, therefore, wish to be limited to thedetails which I have shown and described; but

What I do claim, and desire to secure by Letters Patent of the UnitedStates, is-
